摘要： In a first aspect this invention discloses methods and apparatus for operating a radio link protocol receiver when receiving data blocks from a transmitter. The method includes receiving a data block and making a determination as to whether the size of a receive window is less than or equal to a bitmap size, where the bitmap size is the maximum size, in bits, of the bitmap to be reported in an acknowledgment message. If the determination is positive, then the reported bitmap covers the entire receive window, while if the determination is negative the reported bitmap covers only the beginning of the receive window and covers as many blocks as there are bits in the reported bitmap. In a second aspect this invention a method includes making a determination as to whether the size of the receive window is less than or equal to the bitmap size, and, if the determination is positive, the reported bitmap covers the entire receive window, while if the determination is negative, either a first partial bitmap covering an initial portion of the receive window is reported, or a next partial bitmap covering some portion other than the initial portion of the receive window is reported.
